Question [DEFY MINI] Port Defy Custom Roms to Defy Mini

Hi all. I was just searching around for custom Roms for our Defy Mini (XT321), but I couldn't find any Rom (not even unofficial ones!!!).
Our device has much better specs than the Galaxy Y but still, that has many Roms and Mods, but our Defy Mini doesn't!
Is it possible to port a Custom Rom from Defy/Defy+ to our Defy Mini?
Thanks in advance!
