Swap staggerfeed Model 11 204 to .473

My apologies as I know this has been beat to death...

I know I need a .473 bolt head, and need to address the mag issue somehow...

Can I use all the parts from my .378 bolt head on the .473 bolt head, or will I need something new?

Do I need a new front bolt baffle? Bolt currently has a baffle with a long rearward protrusion, maybe a bolt stop for the 204/223 class cartridges? If I do need a new baffle, will one of the 110-116 bolt heads from Midway work? The 10-16 bolt heads appear to have the long protrusion.

Anything else I'm missing for this question that I'm sure has been asked dozens of times?

Thanks!
