It would take a lot more than that for me to reconsider.
I'm a huge fan of Dennis, but the facts are the facts, Nobody who pays close attention to the pro scene would call the US Open 10-ball, US Open 14.1, or US Open 8-ball major titles. These are, in recent times, small field events and the elite within these disciplines are rarely present. These titles are easier to win than strong regional events like Turning Stone and much easier to win than Eurotour events or the European Championships, which are mysteriously missing from Niels resume, despite his having about 11 of them, all of which should be listed as major titles. Feijen's 9 titles at the European championships should also all be viewed as majors. For most of the last decade, the European 14.1 championship has been the most difficult 14.1 event of the year to win, although I believe Peter Burrows is in the process of changing that. Hence, after eliminating the minor US Open events from Dennis' list of major titles and adding the 20 majors not listed under Feijen list of major titles, I'm calling the major title count as Feijen 26 (I refuse to count the Skins Championship as a major), and Orcullo 12.
I'll add that Niels has probably been a top 20 player in the world for over 20 years. He is the very definition of sustained excellence, and outside of Souquet, Niels has a strong claim to being the best ever European pool player (with Ortmann, Appleton and Hohmann also in the conversation).
If the list presented by Bob Jewett is the one that Hall of Fame voters were presented with, that explains why Dennis got more consideration than Niels, but his career doesn't nearly measure up to that of Niels, who has mass produced major titles over big, tough, fields at a far greater rate than Dennis.
All that said, these two exceptional players will both be BCA hall of famers one day, and deservingly so. I hope I'm lucky enough and healthy enough to attend their HOF inductions down the road.
I have and will continue to contend that, unless this is a case of the Hall of Fame committee being clueless and uninformed, a possibility I'm prepared to dismiss, those who have won the majority of their titles outside of the United States have been discriminated against by the Hall of Fame committee, and it's a crying shame.
