It might work but note that it might also have unknown issues, i haven't tested any trade copier with risk master.
for example the trade copier behind the scenes might follow the leader and if risk master exits the leaders position it might recognize that and exit all other positions as well and alongside that errors could occur..
I don't know how they developed the copiers behind the scenes that's why i advise caution, but you can try it out on sim accounts to confirm first if you'd like!
Best,
