I have 4 routers and I want to use 2 routers with Internet and other two with PSTN,WAN.Is it a good design?

Can I run internet on two routers and if I can use other two routers for sdwan and ptsn line ?

Other thing can be is that attach the switches straight to two redundant routers which have PSTN,SRST and SDWAN or MPLS.I am intending SDWAN because my email and domain will be on cloud.

As per the diagram, I do not see any issue here.. this is cisco CVD advice most of the time.

My advice add one switch between FW and Internet and WAN routers,
