Ya that would be nice but you will either get the original incredible or the incredible 2. Any ways, the original 2.2 downgrade should work. I have tried it my self and I don't see where people have problems. I bricked my phone really bad and had to install the actual bootloader. But point is I had no problems downgrading and rooting again. Let me know if it worked for you. It should since you have a bootloader still.
