Help me decide - Big or small bolt pattern?

I need your advice on something. I've got drums all around on my Demon right now and I'm planning to do the "standard" disc brake conversion in the front this winter. As you can see from the pic I'm currently running all black steelies with the small 5 on 4 bolt pattern, 14´in the front and 15´in the rear and I REALLY like the look of the black steelies on my car so I'm not really that interested in moving to something else. But then again, doing the conversion there's first of all the issue with fitment. I've seen that some kits supposedly work with the 14´wheels just as long as the BS is enough. But secondly, am I just being stupid keeping the small bolt pattern and is it better to just switch to the bigger one while I'm at it? I guess one possible alternative if I would like to go to the bigger pattern down the line is to use bolt on wheel spacers. I'm actually already considering spacers to move the wheels out app 1.5´.

Thoughts?:) Also any tips on kits that you KNOW works with 14´ wheels would be appreciated I'm thinking of running manual brakes btw.

Thanks!
