I don't think BGP has a problem working over IPIP tunnels. In the end it is just a TCP connection to one or mre endpoints.
In principle yes, but unfortunately the current IPIP tunnel implementation handles both the tunnel establishment and the routing. The routing is static. You cannot setup BGP sessions because you do not know the other side's address and AS.
Possibly one could work around that by adding the 44net endpoint address and the BGP AS number of each tunnel gateway, so the endpoints could connect eachother for the BGP routing.
However that would be another major change and I'm not sure everyone would want to BGP peer with everyone else. That could also introduce new scaling problems.

There is the option for a few people with the enough knowledge to configure some route servers. This would then only require BGP peers to maintain a connection to a hadfull of devices and get visablity of all routes
