Victory for the hosts would finally extinguish the dwindling challenge of Oxford United, whose match against Northwich Victoria on the same day would become irrelevant, and hand John Still's men an unprecedented championship and promotion to the Football League.
It is a proposition that Daggers club officials hope will prompt their supporters, and many neutrals, to give up their Saturday afternoon to witness a piece of local non-league football history.
Although Thompson was reluctant to suggest that the fixture would surpass the club's record Conference attendance of 3,939 against Chester City on the final day of the 2001/02 season, achieved at a time when Garry Hill's side were going for promotion, he admitted that number could be threatened come Saturday afternoon.
"We're expecting a bumper crowd. Aldershot will probably bring a few hundred down. After all, this could be the day Dagenham & Redbridge actually go into League Two," Thompson said. "I keep having to pinch myself. We are within touching distance. I don't think we'll sell out the ground or beat the record league attendance because of the segregation policy but we'll go very close to it."
Thompson suggested that despite the magnitude of the match, he does not expect the club to sell the entire 4,800 tickets on allocation but does anticipate the 1000 tickets on sale for seated areas to be sold out by Friday.
West Ham's Premiership game at Arsenal on the same day sold out weeks ago and Thompson hopes the crowd at Victoria Road will be bolstered by floating Hammers supporters unable to get a ticket for that match.
"If you're a football supporter and live in Dagenham and the surrounding area, you'll want to tell your grandchildren that you were there when Dagenham & Redbridge went up into the league," he said.
"We're an Essex/East London club and lots of our support comes from those areas. We have an affinity with West Ham and West Ham fans have an affinity for us."
A 13-point lead with a game in hand has caught the imagination of neutrals and Daggers supporters who have not travelled to Victoria Road regularly to watch their side take the Conference by storm this season.
Thompson revealed that the club had received "50 or 60" on-line applications for tickets on Sunday alone and that a couple of hundred tickets had been sold during the preceding two weeks.
