The idea of football at BT Murrayfield has been backed by Scotland's national clinical director Jason Leitch.
Hearts and Hibs have been in talks with Scottish Rugby Union about using the venue for matches when football returns from the coronavirus shutdown.
And while things are likely to be behind closed doors initially, it is hoped that small crowds could start to return by the end of the year.

Professor Leitch reckons the stadium could be an ideal place when crowds are allowed to return given its size.
He told BBC Radio Scotland's Off The Ball: "There isn't an exact formula but what you are looking at is probably an empty two between everybody, and a couple of empty seats between people from different households. But if you go as a family of four you can sit together.
"I am thinking probably a fifth to a sixth of that stadium, maybe a quarter. Murrayfield have done this, I have seen the chart, they have done what two metres means.
"The good thing about Murrayfield is, it's big, it's accesses are big, and you don't go indoors to get to your seat. Hampden is not dissimilar but Murrayfield is slightly more isolated and on bigger acreage.
"In the conversation we had with football and rugby, they were both on the same call, there was a lot of chat about whether Murrayfield could be a bubble that could host quite a lot of this - behind closed doors first of all, some training and then in the fullness of time have crowds. I think it's an excellent idea. It makes perfect sense."

Professor Leitch reiterated that plans for an August 1 Premiership kick-off can only be provisional.
"This virus works in three-week chunks roughly," he added.
"On average it takes a week to get sick, you're sick for a week and then you're really sick for a week if you are going to deteriorate. And unfortunately people are still dying of this disease.
"We don't know what last week's phase one does for about two weeks and really about three weeks.
"That's why the compulsory legal review period is at three-week periods. It's really important we don't go too quick."
