Suggestions on towel rail piping

[Handieman]

Hi all.

 

Looking for some ideas on how to deal with this piping issue.

 

My current towel rail is 1000mm x 600mm and ideally I'd like the pipes coming straight from the ground into the rail. The distance between pipe centres is 695mm. I can get a 750mm wide rail but the centres with that are 705mm and that additional 10mm could cause too much strain on the pipes.

I guess I am brainstorming out loud here, but would it be feasible to knock a channel out from the concrete and see if a pipe can be adjusted closer 10mm? The piping is 10mm plastic and inside a conduit sheath. 

Thanks
