The Italian, who in 2001 lost both legs in a Champ Car smash, visited Imola last weekend and tried the spare FW27 car's F1 cockpit for size.
The next step is a proper seat fitting in Britain, ahead of a (yet undisclosed) test.
Speculation says the 38-year-old may power a hand controlled F1 racer around Indianapolis in June, or at the Nurburgring a few races later.
It's also suggested he may simply do a 'normal' European test.
"A seat will be made for him soon in our (Grove) factory," a spokesman told f1racing.net.
