Yes and no.
I learnt about the need for an adequate straight between opposing curves whilst running a Rapido APT-E. The ends of the trailers wanted to tilt in opposite directions.
By the time I had grown up enough to try 7 mm, I plugged a Setrack curve into a Setrack point and I could see the potential problem berfore anything got fixed down.

When I used the O scale Peco Setrack, in order to reduce the 6' way I cut a 3 sleeper section off the point curve and the corresponding length off the Setrack curve. This reduced the track centres from 150mm to 105mm - the result is at the bottom of the photo.

Spent the weekend playing about with templates about an idea I've been mulling over for a few weeks, a small micro layout with a scenic section of 4ft 6 and a width of 1ft 6. Possibly using 3 set track points slightly shortened Track plan as below
I have just dug out two Marcway points, these are 48 and 60 inch radius.
Marcway do a selection of tandem points, see Marcway 0 Gauge Pointwork.
One of these would cost slightly more than two Setrack points, but it would consume less space and the 48 inch radius would look more gentle than the Peco 40 inch.

The other gains would be that the curve needed to start the divergence ends when the crossing is reached, and doesn’t continue beyond, which gives you a reverse curve rather than an s-bend, with the buffer locking problem, and the larger radius will be more forgiving for your six coupled wheelbase locos.

I’ve done similar, except that I shortened them by an extra sleeper, so cut four off. Made the angle of divergence shallower and kept the track centres closer together.
