Bonding and vpn at same time

Hi
I have two adsl routers configured in transparent mode ( acting as an adsl modem )
Each of them is used to establish an ipsec tunnel with a respective remote site by use of a netgear firewall
Only one netgear is used as default gateway for the LAN
Is it possible to replace netgear devices with a single routeros device ,still keeping both vpn up and bonding adsl together to increase internet bandwidth ??

Thank you very much
