I have to replace my pump and it seems the builder did not leave me much room.

Right now there are 2 1/2 inch 45 degree fittings attached directly to the jandy valve and a short run of 2 1/2 pvc and another 45 to "straighten" it out. If i cut the 2nd fitting off it will shorten the run and push the new pump into existing gear and really throw off the alignment for the output.

Trouble is the jandy pump unions are connected directly to the 45 degree fitting. I would like to keep the 2 1/2 pipe and elbows for flow through the turns. I will have to run some 2 inch straight pvc, or maybe 2 1/2 and drop to 2 at intake, to the new pump and pump union as the intake on the new pump does not line up. How do I, or can I, re-purpose the 45 degree elbows that are there add a few inches of pvc and the new union?

Cut the 45 at the valve off flush with the valve port, you can measure the distance for the cut from the other valves.. You can then install 2" pipe into the valve. The short distance of 2" pipe you will be using will make 0 difference in the flow, especially with a VSP set to lower RPM. For the most part, all your plumbing is 2" anyway, so that 2.5" added nothing either.

Thanks, yes moving to VSP. So I was hoping to keep the 21/2 to offset anything lost by the 2 45 degree elbows. So do you believe they are not doing that, and is the opinion I would not lose much by cutting it off and using 2 inch pipe and 2 in 45 elbows? I'm not a plumber and wanted to avoid doing the 45s incase I wrecked it and it came out all janky. 😄 If I cut it, how do I know where it's flush?

Would be super if could introduce some sort of union, for future work, but not sure I have that kind of space.

Flush can be measured from the other valves. Usually it is just behind the line marking the bend on the inside of the 45. You will lose nothing of any significance going to 2" pipe, if in fact you do lose a bit of flow.
Your pump has a union. Adding another in front of the pump just adds another 3 spots that could fail (2 glue joints, the union itself) and cause a suction leak.
