Somersby and Sgt Reckless could miss the Aintree meeting in favour of other opportunities, including Punchestown.
Now a 10-year-old, Somersby put in one of the best performances of his career when chasing home Sire De Grugy in the Queen Mother Champion Chase at Cheltenham.
Sgt Reckless was one of the biggest eyecatchers of the week in the Supreme Novices' Hurdle to be beaten just over four lengths into fourth by Vautour.
Connections are still to finalise plans, but Somersby could wait for the Celebration Chase at Sandown or Punchestown, and Sgt Reckless may also head to Ireland.
Trainer Mick Channon's son and assistant Michael junior said: "I'm not sure we'll have any Aintree runners.
"There are options for Sgt Reckless and Somersby, but Sgt Reckless could go to Punchestown, and there are options at Punchestown and Sandown for Somersby.
"Somersby is in really good form. We'll talk to Hen (Knight) about it all, but he hasn't had a long and hard season."
