OT:remote access VPN routing transit

Group,

I am faced with slight problem and am reaching out to see what others have
done on BCP basis. Company A was aquired by Company B and is company B is
advertising to company A and large amount of public IP's that are
internally used by them to access all the internal apps etc @ Company B.
Now the dilema is that all the remote VPN users are split-tunneling a
10.x.x.x/8 which is Company A's entire network internally and need to hit
the parent company B's subnets.

1st thought was to advertise a laundry list of subnets over the VPN for
which users could route accordingly. Not sure this is right approach.
2nd thought was can I tunnel everything and send hem back out FW.

Maybe an easy solution here, but just not seeing it.
any thoughts or has any one had similar scenario?

Thanks group for all your help,
