Can I use two dissimilar wifi nodes to create a single, better WAN?

Hi all, Techy-ish dude here, but limited knowledge of computer networks. 

I've set up a home LAN/WAN as shown in the picture below. Generally works great.



The two wifi routers are creating two separate Wifi networks, with different names, although they do share the same password.  Is it possible to set them up in such a way so that they create a single, wider area, network, rather than the two separate wifi networks I have currently?  They are from different manufacturers, so I'm not sure if a wifi mesh would work, but since I have the cable routed out there anyway, I was thinking there might be a way to get them to play nicely since they're all running from the same LAN?

Is it just a matter of remaining one of them, or would I need to do some fancy IP address renumbering and wifi channel changing?  (I'm not totally opposed to purchasing a second one of either of these routers if it will make it easier, but it'd be nice if I didn't have to...)

Or is this just not possible?

Thanks,
Geoff

does either have the capability to be a wifi extender or a repeater?

I believe the velop may?  It can be set up in a mesh network.  (I actually have another velop node, but it seems to be broken.)

Mixing equipment made by the same vendor can have a few issues, but is generally doable.

Mixing equipment made by different vendors can have so many issues, it'll make you want to just buy another piece of gear from one of the vendors and be done with it. Even though there is an EasyMesh standard, none of the wifi vendors out there has any incentive to use it.
