Typically speaking - porting roms only work when the phones are similar in terms of hardware (many MTK devices do this). The S3 Mini and the S4 mini have completely different hardware, with nothing being the same, it's probably next to impossible (it may be possible, but it's probably a lot more trouble than it's worth).
It's a bit like trying to put a truck/lorry engine inside a small car - extremely diffcult, not worth the labour and money.
