You can use the Linux's multipath feature:
# ip ru
0: from all lookup local
50: from all lookup main
...
100: from 192.168.0.0/24 lookup 100
200: from all lookup 200
32766: from all lookup main
32767: from all lookup 253
# ip r l t 100
default src DUMMY_IP
nexthop via ISP1 dev DEV1 weight 1
nexthop via ISP2 dev DEV2 weight 1
# ip r l t 200
default via ISP1 dev DEV1 src MY_IP1
default via ISP2 dev DEV2 src MY_IP2
You can add to this setup my dead gateway detection
extension (for now only against 2.2):

By this way you will be able fully to utilize the both lines
for masquerading. Without this patch you will not be able to select
different public IPs to each ISP. They are named "Alternative routes".
Of course, in any case the management is not an easy task. It needs
understanding.
