Given the above situation, I would have to say no way!
How can you be sure of your obstacle clearance at night if you are below msa, lsalt,mea etc. Mountains don't have lights, nor do power lines strung between them and are you really sure that, that flashing beacon on top of that 400ft radio mast is still working??
Just because you can see the runway does not guarantee your saftey from obstacles that are out there waiting for you!
Stay above your published lsalt or msa until you are within your approved circling area for the category of aircraft that you fly. eg. 4.2 nm for cat C. etc.
Stay within that area and at or above the circling minima for that runway until you can established yourself on a normal approach profile, with the landing threshold and visual approach slope guidance (if it has any)continually in sight.
