40nm

So I watched @RIP-Felix video on the YLOD and I now recently got three Frankies, CECHE01 (40nm), CECHC03 (65nm) and a CECHA00 (40nm). In his video he said that you cannot downgrade lower than 3.55 on the 40nm models. However, is there any way to modify the RSX or something in order to...

can i put a cech-3004 with its 40nm rsx into a cechc04 making it a frankenstein and still be able to install cfw and overclock it?
