IPSec accross L3VPN - is it possible?

I have two location connected through L3Vpn. On one side is Mikrotik and remote one is Juniper SSG. On both sides I have default route to L3 VPN provider who is routing local subnets. I have request to implement IPSec tunnel between these two location for all traffic.
So the main goal is to somehow all traffic goes across Ipsec tunnel and not to default next hope. On remote side on Juniper is possible to make all traffic goes through Ipsec.
Is it possible to do this on Mikrotik and if so how I accomplish this scenario?
Thanks in advance.

Good question but long answer. I know what you are talking about and we had the exact situation before.
