This wouldn’t work. The primary reason heating and cooling bolts works for their removal is because they expand anisotropically due to constraints and then shrink uniformly. If you remove a bolt in this way and measure it with a micrometer, you will find the cross section has permanently narrowed and the bolt has permanently elongated, an ever so slight amount.

Assuming you managed to install a preheated bolt, it would become looser as it cooled down.
