Twin impeller pump 1.5 bar . I only need one side in theory but could do with more pressure, if a cross link the outlet on one side to inlet on other can I get 3.0 bar outlet pressure? (one inlet and one outlet)
Why would it cause damage, its cold mains water?No you will just wreck the seals on the inlet to the pump.
Adding centrifugal pumps in series does add the pressure together.. but if the seals aren't built for 3 bar plus on the inlet side then it will fail.

Then it would be in parallel and you would have 1.5 pressure but twice the flow.
How is the water heated for your shower?
From a combi at mains pressure?
Or is the shower electric?
You need to give us ALL the details so we can give solutions that you may never have considered.
If the pump is a good quality and they are made in 3 bar versions then I would expect that the seals are all the same and that it would only be a very small risk to put each end in series.
But on the other hand if its a cheap plastic pump then it could be quite risky

Off the mains and 8.5kw.Is the electric shower run from main cold water or tank fed?
What electric shower is it?
