No.
What we need is a decentralized exchange.
That is the problem.
Not more "solid players". I know you meant well by saying that. But truly: Bitcoin needs no central points of weakness.
This is the entire reason it was created. And are we shocked that the failures have been in the centralized elements?
They are *always* the weak links in a decentralized network.
I don't know if Mastercoin Foundation's decentralized network invention is what I am referring to, but the days of "companies" owning "exchanges" and creating a "trust" situation needs to end.
More companies is not the solution.

Decentralized exchange (systems) are not yet technically evolved enough. Though this might be the ultimate road to take, in the meantime it needs more and solid exchanges and clearing houses for BTC.
We need exchanges that are well funded and well managed, not like Gox, which essentially grew out of a gambling platform and is run by amateurs.
One step at the time. I would embrace a decentralized system but it needs to grow naturally. Also, localbitcoins already is some sort of decentralized exchange and available.
