Shouldn't be any hardware issues with that setup, I am assuming the L-56 is Lincolns name for ER70S wire. I'm also assuming nice clean material and 'decent' not perfect fit up.
I use the same settings for a given material range regardless of position. Have had best results keeping wire centered on joint using a slight whip ie. forward backward movement along the center of the joint. Use time at rear of puddle to get desired width, time slightly forward to let puddle solidify just a tad before getting back into it. Travel angle is usually slightly uphill if it applies, depends of situation. I recommend practicing technique/tuning settings flat and then try some practice joints overhead to get the hang of it. You will need a bit higher settings than average to get your puddle to work right. A very versatile technique, once you get the feel for it. Allows use of higher settings on a range of materials.
There will be limits to what you can actually achieve in terms of profile and single pass width but with practice you'll get it. Fun facts, here in Canada we have the Canadian Welding Bureau ie. CWB which looks after testing and qualifications of most structural welding, very similar to AWS stateside, I'm told the test plates are identical. When I left the trade years ago I had flat horizontal and vertical down solid wire mild steel mig tickets, there simply was no overhead test. Couple reasons for that but I digress. Regardless, plenty of overhead goes on in industry but only when there is no other effective option.
Let me know how it goes.

I’ve never had a great deal of success overheading with a MIG. It’s gonna depend a little on what it is and how critical the penetration is and the appearance. I always had issues with the nozzle clogging up with spatter an wire seizing to the tips. And yes, looking like crap.
Have a lot better of a time welding with stick out of position than MIG, especially when using 3/32” 7018 rod set somewhere around 90 Amps on 1/4” material.

I prefer to wear no shirt and do it in flip-flops.
That way, when I mess up and get drips of molten metal, I really learn my lesson fast.

My personal preference is to turn it up a bit, and just go like the devil. Keep backing back into the puddle to "push" it up into the joint. JUST KEEP MOVING!! That being said, my overhead is still never flat and perfect like flat and vertical can be. Even when I did my cert plates in school, my overhead wasn't all that pretty looking compared to the others, it does tend to blob up a bit more.
I would run 0.035" wire with that thickness of steel and turn my machine up when welding out of position.
