The Girly is too small for me

[Ossian]

When I was younger and more flexible I could adapt to my bike, but now I find I have to sit on the rear seat to be comfortable and of course the ridge at the back of the front saddle causes agony.
So what I am asking is does anybody have a really scruffy front seat for sale that I could adapt to my requirements ?
I really don't want to chop the (original) seat that I have as it is in pristine condition.
My plan is to bond the two seats together and make a contour to make it easy to move around (front to rear) depending on where the aches and agony may appear !
