taking out a small parent PLUS loan right now to ensure i get grandfathered in

hello,

i haven't had to have my parent take out parent plus loans yet in my college career, thankfully. but i just came across the news that after july 1st, those loans will be significantly reduced. since there's a small chance i'll need to have my parent take out these loans in the future, i'm looking for ways to soften this blow.

one idea i have is to just have my parent take out a really small loan right now, before my spring quarter. thus i'd technically be an existing parent plus borrower come july 1st. that combined with the fact that i'll be continuing at the same university means that i'll have 3 years of the current parent plus limit, right?

is this a valid plan?
