Great in principle but in reality logistics geography social distancing would all come into play.Logistics would include several hundred staff, accommodation, travel medical support Health and Safety etc.

Geography include all the above possibly consider the same venue but then what about player isolation etc.

Social distancing and quarantine looks a bit of a big issue even with testing which would have to be daily given the incubation time and also the potential for those that carry the virus but show no symptoms. Given the fact that there is no working anti body test it will be difficult.

It's not impossible but it's not easy, then other issues to consider are the players and all others involved and contact with families.

Glad it's not my headache

I would suggest Headingley.
Its fairly central, has been refurbed and they could use the facilities "next door" at the cricket ground for players and staff etc including the cricket outfield for warm up sessions.

If it was a goer, it would need to be somewhere central and available, with a decent amount of changing facilities.
Any constraints in warm up areas etc would at least be the same for all sides.

Ideally, it should be a venue which is neutral for all sides and somewhere well suited to TV requirements.

Even somewhere like Dewsbury or Leigh may be ok ?

I dont think a neutral venue makes that difference.
I suggested Headingley as it would be large enough for several teams and using the cricket facilities.
Dont think Dewsbury or Leigh could cope with the numbers.

Excellent venue and given the circumstances, if it were to happen would make it the most obvious choice.
