Back in the 486 days, a company called Cyrix created an adapter that would plug into the socket and allow you to replace a DX2-50 with a DX4-100 (or something like that, I don't recall exactly). I actually did it with my AST desktop, but that was almost 30 years ago. There hasn't been anything like that since.

http://www.tomshardware.com/reviews/processors-boards,520.html it just one example in a 1 minute search
in old days the memory controller was outside the CPU ... and there was no PCIe lanes coming out of the CPU.
forget it, such Adapter even if some one tries to make it , will cost you more than a new motherboard.

as simple as that.
ye simple is that you buy cpu and motherboard so its $$+$$$ oh ye memmory
well , motherboards are cheap today not like old times .. you can get a new generation motherboard for as low as $100
any adapter you make will cost you $100 as well , for the memory slots must be on the adapter board and ou will need the new memory as well.
the only pins that you will keep are the PCIe lanes and the DMI lanes (if the same) and the power pins ...
it will be expensive
