as all I need it pressure, and not that much flow, i could play a bit with the opening in the closed impellor. Start small, and then open it untill it's to much for the pump to handle.

Do you already have a closed impeller?
The price difference between open and closed impeller pumps may be due to closed impellers simply being more expensive to make. An open impeller is a simpler construction.
Though it would be interesting to try an impeller converson, I think just buying a higher pressure pump will be the cheapest option in the long run.
