Curved Turnout Radius Help

I am thinking of a redo on a portion of my lower section. Where there was a straight and a LH turnout, I am thinking of replacing with a curved turnout. This will give me greater flexability, and a bit more realism. Peco's SL387 18" inside radius turnout would get me close but it won't be pretty in execution. It is a bit shallow.
Fleischmann's 22273 looks better suited but they don't seem to offer any specs on radius. Can anyone help?
The track I am looking to replace is an Atlas 9&3/4. If I can find something in the 11-15" that would be money.

FWIW it is possible to adjust the radius of commercial curved turnouts to a certain degree.  I did this extensively with my Shinohara code 70s on my current unfinished layout, and they worked well.  What one does is remove the webs between the ties as needed, and then gently bend the turnout to the desired radius.  This works up to a point, even though the frog remains the same.

Maybe one of the great switch builders on TRW could offer up their services to build one for you.  :D

Minitrix "R1 and R2" curved switches were 7 1/2 on the inside and 9 3/4 on the outside.    So I 'think' that "R2" is 9 3/4.   I bought a couple of them on Ebay for my logging module.   Took a lot of work to get them consistent.

I think they also made an "R3 and R4" combination.

That might give you some clues here.
