Power Ups like Assists?

[Alex Mercer]

Higher tier Assists allow for multiple lower tier Assists at the same time. I'm curious as to why Power Ups can't be done the same way? I've looked, not only do the two have the same prices, but even if you had 4 T1 Power Ups with any of the boosts, you can't break any of the rules EXCEPT the one saying "Only one transformation."

Combinations increase drastically if you include Powered Up Forms (Also same price.) Obviously you can only have one Powered Up FORM because it involves altering base stats.

I'm trying hard to think of a way to break this, but so far I can't find a way. >_> And before you say anything about Boosts, it's a 1/2/4 ratio all the way through, so using four T1's with boosts always equals the same as using one T3 with the same boost level, so this balances itself out no matter how you stack it. Here's an example of a T3 with the first boost level:

ATK 8 + 3 + 3 + 3 = 17
DEF 7 + 2 + 2 + 2 = 13
SPD 1 + 0 + 1 + 0 = 2
TEC 0 + 1 + 0 + 1 = 2

17 is half of 34. The above example is assuming that EVERY T1 power up idealizes one stat, which defeats the purpose BUT it proves that the system can't be broken.

Pros of this variance:

• A character with T3 Power Ups has a LOT of variance when they choose to use T2 (six pairs, without counting Powered Up Forms) and a crapload of T1's that I don't even want to count.
  
• More fodder possibilities, such as drinking two out of four of your potions at once.
  

Cons of this variance:

• Cost. T3 would cost effectively 4k, where a regular T3 is only 2k.
  
• T3 doesn't change much, neither more or less powerful than regular. Unless more Powerups of lower levels are purchased to add variance. This yields diminishing returns.
  

Am I missing anything? It seems a hell of a lot less complex than having four sentient minions running about. Is there a reason this is not allowed, or has no one questioned it before? I just think it'd be pretty cool late game to have a way to modify your mid-tiers. Aang might do something like this four each of the four elements with Intigration.
