Single router for P/PE functions

We're trying to save on Transport links. Instead of multi-homing each PE to 2 Ps, we're considering building a ring: P-PE-PE-PE-P. This ring follows the transport ring. Each link would be engineering to make sure it can handle all of the traffic from all 3PEs in case of a failure. As the network grows, we could get individual transport links from PE-P.
Apart from bandwidth, I was curious if there were other problems I related to doing this that I wasn't thinking of. Thanks for all the replies. Much appreciated.

Kinda depends on what you're doing exactly, but like Erik said, it certainly possible and depending on your particular needs, it might not be much of an issue at all.
Can you describe your scenario a bit more?

We're considering doing this as a temporary workaround but we all know temporary usually lasts a long time. I'd like to know what kind of mess awaits if we let this one go.
