I'm working on my 1913 and am considering raising the tank about 3 inches as there is room in the new body to do that. The idea is to not run out of gas on hills as easily.
I know that the shut-off will be higher and more difficult to access. Also the car will be able to go up steeper hills so a working external oiler may be necessary.
I can't see any problems. The extra fuel pressure at the carb will be minimal but could help with a tank low in fuel going uphill.
An extra suhtoff at the carb would solve the access problem. I installed mine along the frame near the passenger floorboard in case of an engine fire (I didn't want to be opening the hood and sticking my hand in there to reach the shutoff valve). I access my shutoff valve (lever type) through a 1" hole drilled in the passenger floorboard just above the valve. The floormat covers it.
As you are clearly handy with wood work, I would suggest building in a compartment below the tank with the door opening at the front. This would give you convenient storage and easy access to the shut-off.
Terry, before you fix it permanently, get your seat cushion finished, fit a temporary backrest, and make sure you have a driving position. You will certainly have less room between your thighs and the steering wheel. One thing in your favour is the smaller diameter of the 13 steering wheel.
I have found when building custom wood bodies the there are certain constraints which mean all bodies are reasonably similar in floor board risers, seat heights and set back, and backrest positions.
Hope this helps.

This is a reproduction of a 1913 New Zealand produced body. I've already sneaked in the only departure from the original... I slid the front of the seat back 2". I'm not a large guy (5'8") no way I can fit under there as they did in NZ! The body is a dry fit up right now. Once I have the floors and the seat done I'll put a cushion in place and sit in the shop making fire-engine noises.
The tank position won't effect the seating geometry. In the last 1913 I did I left the tank low and built a tool tray on top of the tank... leaving a hole to access the tank bung.
Compare the size of the fire brigade men compared to the 30" wheel... none of them were giants. The helmets add about 6" onto their height.
RHD in USA ???
Alan l just picked that too, or is it the angle of the photo ??
David, it is RHD. The pedals are visible on the right.

That driving position looks uncomfortable to me. The wheel is too low, it's in his lap! I think I would prefer to err the other way. Much easier to reach up then squeeze in. ~~~Just my 2cents~~~~
Terry: My tank on the '13 Speedster is about that level... no problems.
ps: I still have the all white smoothies for your project
Thanks bill, that is what I needed to know.
the 26-27 coupe tank still higher
