Indeed. I was concerned of what to do if I couldn't get my Phil 3s from Jim... so I started looking for something to use as a full-range, 3-way replacement.

Fortunately, Jim and I came to agreement, and I didn't have to do that as my first DIY!
(I had also hedged my bets about the Phil 3s by asking Jim about sending me the finished cabinets and all the parts to assemble myself.
Thankfully... Not necessary.
I will say, though, one gentleman from the two forums did order a customized center channel kit from Rick, since the gentleman couldn't get the center BMR... Seems to be happy with the outcome thus far... is supposed to be building the cabinet while rick makes modifications to the XO.
Hoping a build thread gets posted with some info!
