Can I use Hongmi Red Rice' WCDMA ROM version on TD-SCDMA model?

Hi,
My friend bought me a Xiaomi HongMi Red Rice from China.
Unfortunately, it's a TD-SCDMA model one that doesn't support my 3G-WCDMA' SIM system.
Is it possible to make this phone to work on WCDMA system by replacing with a ROM of WCDMA model one? Any advice?

Thank you,
