QUESTIONS:
1- To reduce the possibility of harming the neck, should I use low tension strings or...?
2- On the other hand (and never mind the risk of harming the neck), would medium tension strings be more likely to give me better resonance at G to G tuning?

Increasing tension that much is more likely to pull too much belly into the top-- south of the bridge, if not a challenge to bridge attachment. I used an online string tension calculator to find that you will be increasing total string tension by 40%. Play around with it, and check my work. Link below.

I used these inputs for the calculator, which may or may not reflect your setup of a 3/4 size guitar, which I know nothing about, so I used more (toward) conventional sizes inputs.

Scale length, 630mm. String gauges, .043"to .028 (a preset in calculator, I forget the in between gauges, but all standard.) Tension: 83.9 lbs at standard tuning.

Change to tuning G2, C3, F3, Bb3, D4, G4. New tension, 118.7 lbs.
