Alloys should be glass blasted, not sand blasted ... as I was told by the guy who straightened my Hartge wheels.
Sand is too harsh for them.

sand-blasting with create lots of 'pin-hole' type inperfections which will take alot more effort prepping if you want a perfect finish.

I work for a company that does, amongst about a million other things, blasting and painting.
Sand/grit blasting will be fine as long as a fine grit is used (Olavine) and at a reasonable pressure. If the guy doing it is a muppet and just goes hammering in then you might get problems with surface erosion. If it is an experienced blaster and he works at them slowly it wont be a problem.
Any fine surface roughness will provide a good key for a high build primer which will fill any small imperfections anyway.

Would BBS's come up well powder coated?

There is a bloke near me who says he can take the tyres off, blast back to clean bare metal, powder coat and re shoe/re balance for £150 for all five.

I think he is thinking of more gaudy colours but can you powder coat them or would the center caps not fit and generally look crap? Should i just lacquer them after blasting?
