I am sure it would help if the flash points towards an internal reflective surface. I use one where the flash pokes through a hole in the back, therefore the flash head is pointing straight forwards at the subject (as it would be on a shoot-through umbrella also). So in my case it is important to scatter the light in all directions to achieve the softest and most even effect.
With your type of box it may not be as important, however having the light hit and reflect from all internal walls would be preferable I believe.

I think the loss of power is caused by the extra spread of light the diffuser causes, and with a flash alone this spreads all around a room. However inside a soft box the light is captured and concentrated and confined to the angle of coverage of the box, therefore no power loss. Without a diffuser most of the light is projected forwards, whereas to work best the light has to bounce evenly off all the internal surfaces. That’s why they often have refective silver on the insides.
Try it out, it’s worth experimenting with to see if it has an impact in each particular scenario.

A single flash won’t spread the light widely enough inside such a big soft box. Even in my 24inch box I add a Gary Fong Lightsphere to the flash head in order to send the light in all directions. Soft boxes work best (ie softest light) when the light hits all four walls evenly, not when it’s projected mainly forwards. So I’d suggest fitting some sort of dome type transparent diffuser on the flash inside the box. Without this you are likely to get hotspots and uneven light across the area covered by the box.
2 flashes inside one box or umbrella will be better, with a wider spread, but still has the issue with hotspots from the centre of the flash head.
CJones is rIght about avoiding full power ...... these flashes are not super performing in terms of recycling, and you’ll end up changing batteries mid shoot as well . For something fairlly intense like your event then keeping to 1/4 power will give more comfortable performance. You adjust other things to get the desired exposure ....ie distance from flash to subject, aperture, ISO.
