I fully understand the emotional part of this. The rational part however is that a bigger enclosure will give you a terrible highpass slope at frequencies usually chosen for transition to a sub, unless you’re into pretty complex DSP countermeasures.
A few years ago I rushed through the construction of a pair of Jeff Bagby designed Mini Revolutions using all SB drivers and although they are solidly built they are not really up to my usual build quality and I intended selling them and build a keeper pair as they to my ears sound among the very best. Any way I ended up keeping them still consider them fabulous and although I regret building them in a hurry they sound so good I am glad they did not sell.they sound great when played alone with among the most coherent bass a 4+" driver can manage [probably due to the racetrack passive radiator]and I do pair them with a pair of BK monolith sub woofers to very good effect. I can solidly recommend this project.

I recently revamped my SB15MFC build; They're in 12L tuned to ~41 Hz, port is 40mm dia x 160mm long. I run these with a .5 way woofers rolled in at the baffle step freq (600Hz), they integrate very well. I tried something different for the xover, just knocking down the MFC's peak at 6KHz with a 0.33 mH inductor, but nothing else, so essentially full range. The tweeter (SEAS 2TBFC/G) xover is 3rd order @ 2Khz. I am very happy with the result, they match my reference system very well for sound quality with the woofers, having a rich mid bass, & perform great alone as desktop speakers
