Fernalfer - yes, you can make that stand work using flexible tubing, which is not what your hoping to do.
Or
You could build a stand to your specifications.
I would personally take the time and effort to build a better stand in your situation. I think you would benefit in the long run from the increased size and aesthetics of a custom built stand. You could even design to larger than the footprint of the aquarium to meet your equipment and storage needs.
My main reason for suggesting this is if you went with the current stand and crammed in all your equipment to the point that it's difficult to maneuver for maintenance or simply to clean a skimmer cup, you simply won't do it for the long term.
Many of the long term successful systems on here are successful because they have minimized the effort required to perform normal maintenance tasks. If it's a struggle everytime you need to complete a task in the stand, you are less likely to do it.
This is my opinion and I hope my perspective is helpful in your decision.
