Flashing Radio for 4G LTE Bands

I have an XT1058 in Pakistan on Rogers 5.1 ROM but the LTE band used here is band 3 (1800 MHz), which the XT1058 does not support. I haven't tried running LTE on it yet but can I flash XT1052 (Europe and Asia Retail) radios on my phone? Or flash whole SBF? Is there any way to unlock band 3? Would it brick my phone?

@KidJoe Please help.

Thanks
