I think adding the other routes and difficulties isn't a bad idea as other Rider games have all their options as categories on the leaderboards like Agito and Blade. With my time being beaten recently I'll be looking to come back to challenge that when I have the time to grind, but having more options for all runners would be a great way of letting people play with who they want.

Just comparing the 3 runs on the board, both the PC load after hitting start at around 6 seconds before the black and white Bandai screen appears whilst my version on switch takes almost 20 seconds. If you then look at the load leaving the base for the first time the PC versions are around 4 seconds with the Switch being around 16.

As there are a lot of loads between each stage, this can easily add up to a lot of time saved. In my no continue/no base run there were 21 load screens, 1 being the initial loading and 20 stage loads. If you work out just the loading times using the above numbers, the Switch had 340 seconds of load or 5:40 with a PC run clocking in at 86 seconds or 1:26. There's a lot of RNG when it comes to items and fights which will affect everyone, but with the Switch already starting at a 14 second disadvantage and that number continuing to grow throughout the run I personally think a split would be best to encourage people to play on the platform of their choice in a balanced environment.

I think adding it would be fine and would allow for some new ideas and strategies to be made. If there's editing to be done with the board might I also suggest splitting PC and Switch as there is a considerable difference in load times across a whole run which leaves console players at a disadvantage.
