You MIGHT be able to fit it in, but the chances of a short with the wall is very high. If you do manage it and there is still sufficient clearance between the wall and the coil, I'm sure your ID falls within mini coil range. Not that it matters what your coil is called, but just to clear some misconceptions about micro
coils.
1.6 ohms with 28awg kanthal is the highest I am able to get on kanger t3 with a micro coil. Lost count of the number of wraps.
28awg would also take too long to heat up on a vivi at 3.8 volts. Under load, the voltage is gonna drop much lower. I would suggest 30awg instead.
