Greetings Strelok
We are brothers by the second syllable
Is your question simply about the reverb driver stage? LP push-pull versus the everyday SE? I think Mr.O'Connor's description of the benefits of push-pull driver are all you need to know and then just look at the cost each way. Apparently one can acquire a "Fender" replacement reverb drive transformer for just a few bob and from a plethora of sources. There is a custom reverb drive transformer on the London Power site which is more expensive, although Mr. O'Connor kindly gives you alternatives in TUT2, referring to Hammond's 125A as a reasonable candidate.
One thing, too, is that the reverb path is what Kevin calls a "side-chain", which suggests that maybe the fidelity does not have to as high as in the main signal path? That may not be true for effects loops, but I think it is here? This may influence the transformer choice.
If you are building a stereo reverb for general use then maybe the reverb quality and noise are more important.
Cheerio
