In Hyper mode, the minimum requirements (apparently) are:
Just looking at the requirements I'd say some of the requirements don't seem to look too bad.
I just took a quick look at hyper but I don't have the necesary funds to complete it so I'll be parking my unit at week 11 again, though I've sped up the weeks a bit by taking a few weeks off to spy on the 2nd release chart requirements.
With the old dual appeal route it's possible to rank in the top 50 easilly, if you continue with the usual schedule you should be able to get 56k fans with your 2nd song in week 17 without obtaining any of the special states, thus ranking in the top 20.
Getting idol rank 16 should be easy enough, training stats seems to be as fast as normal and 360 ver though actually raising in image level seems to be slower, this however shouldn't be too much of a problem assuming you have money to burn, which I don't, I can't spare 15x 30k money yet..
If I had the money I'd be doing paid promotions, I'd also be able to somewhat continue training, get memories and obtain more fans than usual, meaning getting an S rank would involve a lot of funds. Might be better for people at later playthroughs, but assuming you can't reach producer rank 10 before finishing with all the idols I'd say it's rather pointless trying so.
As for scoring I've gotten 70k with megare on the 360 ver before using dual appeal, so 65k should be easy enough. With a proper set up getting 76.5k should be possible.
Of course the weakness for dual appeal is it's inability to score well so we need to ditch it somewhere along 3rd-4th song.
Below is untested but should work in theory.
Because we have tons of extra memories due to spamming paid promos we should be able to replicate the strategy used by certain Vesperia units; spam bursts.
This is where switching to May Queen comes in. Some Vesperia units seem to be using an Ataka or Yamahara voltage boost, do a couple of regular appeals and afterwards refresh their modifiers and do a clean 2.2/2.2/2.2 burst
Though it seems like it doesn't matter who you use to burst I'd reckon using Hibiki would be best as she leaves you with a 1.3 multiplier for Da. Chihaya got nerfed from 1.3 to 1.2 Vo so she'd be a 2nd choice just like Miki with 1.2 Vi. We can do a couple of appeals with the declining 1.3 modifier and refresh it with a mem appeal again.
If we assume we want to make Hibiki our main attacking force and if we don't want to make our earlier training go to waste I'd guess it'd be something like
Unit Hibiki/ Miki/ Any though I'd just go with Chihaya
W1-7 Rank in top 50, obtain Koshiba in w7. Go with Awanko charm and go Vo/Da dual route. Miki for burst. Train Da.
W8-16 Train Da, obtain Koshiba in w15.
W17 Rank in top 20 with 2nd song
W18-? Farm fans by doing paid promotions and a training. Train Vo until reaching image 16 if Da is maxed.
W3x switch from dual appeal to May Queen.
Because we trained Da back when using dual appeal we have a pretty high stat for that, Vo should be pretty nice as well, so do a couple of Vo and Da appeals, reset with memory, Burst, repeat. You should get around 16-19k points per burst like this if you obtain more danketsu. Also, seeing as how you bounce back to neutral after w10 and you don't lose kashimashii in w21 if you already had it, I'd say one can obtain 10 danketsu or so more than on the 360 ver making bursts slightly stronger.
Some Vesperia units seem to use mushaharu+reporter voltage boost. This seems more effective when playing Fes's whereas the above seems to be better for everything else.
Still, I don't know how the above schedule would actually work out when actually playing though.
