I like the way this revolver looks but think updating it to modern features would be interesting.....make it side opening rather than break top.....make it drop safe.....does anyone make one like that?

Trying to update that particular gun would take so much rework that when you were done it wouldn't be the same gun anymore.
Could you get one made from the ground up.....? How much would something like that cost?
You MIGHT be able to make one from the ground up, dunno, you'd have to check with a gunsmith.
But, because it has the break in front of where the bullets are held, and you said that you want it to release to the side, by the time you built it to your specs, it would no longer be the same gun.
Probably a cheaper option would be to buy a modern day revolver with a side release and see if it can be modified to what you want.
Changing a front break revolver to a side release one is like saying you want to convert a large 4wd truck into a car, or vice versa. It can be done, but by the time you're finished, it's only barely related to what you started with, and isn't quite what you wanted it to become.
