That idea was suggested for the first event in 2017, but your comment was that the events should be kept separate -
"The QRPTTF event on 22 April 2017 was mentioned as a possible NA-EU S2S event. But realize that QRPTTF is specifically and fundamentally a QRP-only event, which means maximum power of 5W on CW and 10W PEP on SSB. If the power guidelines can't be respected, the events should probably be separated."
Presumably having experienced both, you have changed your mind.
