He would need to make his own proposal, it is not up to witnesses or anyone else for that matter to do so. I suggested it many times publically he should rather than these posts.

A witness would be the last thing I'd do for funding for it. It will likely end up costing money and the time and effort will remove any chance of profiting from it. I'd rather see him developing (which he is very good at) than maintaining witness server(s).
