EIGRP Floating Default Route Question

Hi Guys, looking for some advice on the best way to skin this feline:

As you can hopefully see I have a MAN which I'm migrating from MPLS to SD-WAN. Previously both MPLS circuits terminated in SiteB but now we've split our circuits between SiteB and SiteC.

The SD-WAN Routers aren't Cisco and can't join the EIGRP peers, so the Routers attached to them will have to have static routes to 0.0.0.0 and have that redistribute into EIGRP.

I was going to define a delay onto the interface between EIGRP R3 and it's SD-WAN router and let metrics calculate themselves out, but my colleague just pointed out he doesn't think a 'redistributed static' will look at that delay to calculate it's metric.

All router's currently have 'redistribute static' under their EIGRP process... I think the best thing for me to do is to change that to ' redistribute static metric K1 K3 K4 K2 K5' on either R2, R3 or both to ensure that traffic normally lands at SiteB SD-Wan router unless it's interface is down then it should land at SiteC....

Thoughts and advice very welcome, thanks in advance.
