Why not use a flat top section, then a 1" thick piece of plastic as the 
insulator, and then

<<I am planning a 160m vertical with elevated radials, using Rohn 25G tower
sections.

Years ago Array Solutions had custom made insulators for Rohn 25.  You might
check with them.

##  My concern with those solid fiberglass insulators is.....   any water that 
comes down
the inside of the three tower legs   will NOT get past the solid insulators 
that are inserted 
into the legs.   The solid insulators of course are used to splice two rohn 25  
or 45  sections
together.   Water  will  collect and collect and collect, and ditto with any 
and all condensation. 
Then when it dips below freezing, ice forms and the legs can slit wide open, 
etc.   Or the 
legs will eventually rust from the inside out. 

##  To use those solid insulators,  you would 1st have to drill a 1/8 inch  or  
5/32 inch hole on the 
inside of each leg, and slightly above the insulator.   Either that and or use 
a modified solid insulator 
with a 1/8” hole down the inside of each insulator.   Even then, debris could 
easily plug em. 

##  Dunno what rohn uses to get around this problem with their megabuck 
insulated section.
