Speaking to The FA.com, Houchen said: "I was offered a ticket by the club's supporters association for the game against Chelsea but I can't make it unfortunately," said Houchen.
"But I would love to go back to Wembley and meet up with the rest of the Cup-winning squad if we could.
"It would be great if Coventry beat Chelsea and then invited all us old boys down for the Semi-Final.
"The whole town is buzzing with excitement and I must say that I would not be at all surprised if they managed to beat Chelsea.
"Coventry are a young team with a lot of enthusiasm and with the fans behind them, I wouldn't be shocked if they pulled it off.
"We were underdogs going into the game against Spurs, because they had been there and done it all before.
"We had beaten them 4-3 earlier in the season, so I knew we had a chance of winning the match. "And obviously, after the run we had been on, we were confident of winning and so it proved.
"Nowadays, the gap between the likes of Coventry and the big teams is much bigger, but The FA Cup is a great leveller.
"They've got a chance and with everyone behind them, I would not be surprised if they did it."
