I am afraid if Alito, Roberts, Thomas and Scalia are not to your liking, I think you might find your future SCOTUS wishes are beyond reality.

I just want a guy that bases his rulings on what the constitution actually says rather than what impact the ruling would have.
We have a means to amend the constitution so whatever impact the ruling would have shouldn't come into play. If the impact is that bad for the country then the constitution can be amended.
For example, Scalia and Rhenquist would often base 4th amendment decisions on whether their ruling would make the jobs of law enforcement easier or harder. This is totally irrelevant - the only thing that matters is the constitution.
Do you think that is too much to ask of a supreme court justice?
