Routing to external Gateway

[max33]

Hi everyone, I need to deploy a specific routing and I not sure that I could handle with pfsense.
Long story short , i got my pfsense as main gateway and a second gateway connected to a specific mpls network.
All internet traffic need to got with wan connected to pfsense and specific traffic need to go to mpls gateway.
Not difficult so long I just need to add in routing a route to specific gateway .

I add first complexity and got a vpn tunnel connected to a second site with same schema as a alternate route for MPLS traffic.

Second complexity

I not able to change ip address of Lan site 1, LAN site 2 neither MPLS one
LAN 1 is 10.19.54.00/25
LAN 2 is 10.19.54.0/25
MPLS is 10.0.0.0/8

Both site use MPLS connection to get acces to specific server located on MPLS network of huge network (a worldwide car dealship)

The two site belongs to same persons and I want to get a vpn between site in order to offer high availability in case of failure of MPLS connection in site by routing traffic of site which get MPLS failure using this VPN.

is it possible to add 10.0.0.0/8 route on both site to specific gateway and add another route with only the /25 or do I need to explose the /8 in several rules in order to not overlap ?
