Can you use more than 1 PP ti increase Temporary HP Aegis Toughened Suit feat?

Build the ultimate damage sponge with a good enough Damage Resistance and THP. I have Aegis Lv 5 with 16 Int and 14 PP (total with high Int mod). I plan on using at least my Lv’s worth of PP to try to get 25 THP and DR of 4/-.

Wait are Aegis still limited in spending PP equal to their Lv? I think this question is pertinent here.
