If the speed of light is 62x higher than what it was, it would allow us to accelerate for longer to reach speeds that would otherwise be superluminal and thus violate Relativity, but it wouldn't change the amount of energy required apply that delta-v.

Agreed energy is not the problem, for wedges. But power is: to accelerate an equivalent of 62x with the same mass and achieve 62x the end velocity, you need 62² x the energy in the same amount of time, therefore 62² = 3844 times the power.
I was going to post that a neat explanation for this would be that mass decreases as one transitions up, such that the rest mass energy E = mc² remains the same. Or, rather, the more complete form of E² = m²c⁴ + p²c² (where p is the momentum). If we keep E the same, ignore the rest mass, but increase c to 62x its previous value, then the momentum must have decreased by 62x. Then, if the velocity changed up by 62x, then the mass must have decreased by 62². The same calculation can come from a simple kinetic energy formula of E = ½ mv²: if the velocity is 62x what it was before, then mass must be 62² less so the energy is the same. This would allow rockets and anything else powered by known things to still work in hyperspace, but achieving the effects we know or expect to be true.
Note Newton would like to have a word: if the mass of two bodies is 62² less and they're still at the same distance, then the attractive force between the two would be 62⁴ less, so everything would just fly apart, starting with electrons around their nuclei. To keep both Newton and Coulomb happy, we'd have to adjust the universal gravitational constant too, probably a few others alongside, like the permittivity of vacuum.
