Sources have revealed that negotiations to purchase the HRT company and secure an entry are at an advanced stage, and the plan for a team known as Scorpion Racing appears to have the blessing of F1 supremo Bernie Ecclestone.
However, AUTOSPORT understands that the FIA believes the 12th entry slot for 2013 was closed off when it was informed at the end of last season that HRT had been liquidated.
Although the governing body is aware of the plans for Scorpion Racing, it does not appear to have any intention of making a special case to allow another team in for 2013 because the entry deadline closed last November.
The investors behind Scorpion Racing are hoping to complete due diligence of the buy-out plans in the next few days.
That means the viability of their plans should become clearer by the end of the week.
Scorpion is hoping to run its effort from a facility at Silverstone, using updated HRT F112 cars that will be powered by Cosworth engines and use a Williams gearbox.
AUTOSPORT has learned that discussions have taken place with Ecclestone about the idea, and he indicated to the outfit in a letter last weekend that if its takeover of the HRT assets was complete then it should get an entry to F1.
Ecclestone wrote to the Scorpion Racing investors saying: "Have you bought the HRT company? Because if you have, they [the FIA] would be accepting you."
It is not clear if there is any mechanism for Scorpion to secure a place on the grid if it can convince the FIA that it has the funding and technical capability to compete in 2013.
