Probably not easy to upgrade it. The MOSFETs that are on that board probably have a maximum voltage rating, likely something like 40V (for a 30V maximum rating). You would probably have to replace all the MOSFET chips. If you can do that, then you have to check the gate voltages. Your current board may be driving the gate between 10V-20V. Increasing the overall voltage may also increase the gate voltages. That means you may have to change gate resistors as well.

It has a very soft start. Do you think if there's any way to eliminate that? It has a 555 timer on it.
