Can these themes work as a shop to sell products and services?

I need good looking community,forum,corporate intranet theme type but that offers and sells services and products. Can it be done with the following themes if I add Marketpress to them?

See the themes:
Blogs MU,
Scholar,
Magazine,
BuddyPress Corporate

Thinking about the features listed above, except for the looking, which one would you choose?

Thanks
