Running a EoIP tunnel across both the T1 and your link you should be able to load-balance across both links for incoming and outgoing traffic by bonding both EoIP interfaces at the customer site and your Mikrotik box. I have done this in the past but it has been across a couple of wireless links with similar round trip delays. If you use per-packet load balancing there may be issues with packets arriving out of order but if you do it per session it should work fine. With per session load balancing you won't get an aggregate throughput of both links with a single stream but should use both links if multiple streams are flowing.

I have a high school who has bought a connection from me but is also stuck with an old T1 circuit under contract for the next 3 years. They want both connections to be used all the time and for all traffic to automatically go through the working connection if one fails. Basically they want load balancing and failover. All addresses are nat'd private space IPs. I would think I should be able to do this with Mikrotik and/or Star OS but I do not know how. Your thoughts and or other suggestions are highly appreciated. If only failover or only load balance is possible then suggestions on that are welcome also. By the way, the T1 provider is not me and will likely not work with me unfortunately. We have to leave their network settings intact.
