There is also the option of jumping to a used SUP2T or a SUP6T in your 6500 chassis. Depending on the line cards you have, you might have to replace some of them.

For a non-cisco option, the new Arista 7280R is somewhat interesting. Handles BGP full tables, has great port density, relatively affordable.

FYI, the version I am currently running is 12.2(33)SXJ1, and though I know it's not the newest thing going, it for sure has served us well with an uptime of 4 years, 51 weeks, 4 days, 19 minutes as of this message. I have little doubt that a reboot may free up some memory, if nothing else some more contiguous chunks, but from all I have read here recently, with taking full routes this is a short term stop gap measure at best. So what I am trying to figure out, is what is a good path forward that will last more than a couple months at best. As mentioned below, I have looked at just using the RSP720-3CXL as it will take a lot more RAM reduce running on the edge of a memory allocation failure (plus the faster CPU is good for BGP). I have looked at using something like the ASR1004/6 as with a full load of RAM it says it will easily do 4 million routes. Finally I know someone that has a GSR12404 that suggested I use it, and though I know it's not new platform, I can't for the life of me figure out what routing limits it has. I for sure need 1G and 10G interfaces (not a lot), also need 32bit ASN support as we already use it at the IX The reboot of the current switch would be easy, but if I need to take the time to haul around big switches/routers, and changing the network around, I figure it just makes good sense to learn what I can to make an informed choice as much as possible.
