This seems to just state that it's "five Digimon coming together". Now whilst Google Translate can't be 100% trusted, even that doesn't mention the other Digimon for X5B specifically.

""Tenshin Buddhist form" that Berzebumon gave power even more to Shoutmon × 5 which five Digimon embodied. A large firepower of Beelzebomon is added to the full power of Shoutmon × 5 which boasts the Musou in the ground and in the air, and the total battle power has jumped several times. Bursting crusher ripped, enemies launched with meteor impact, continuous striking technique that pierces the finish with chaos flare "burst dash stream" battle enemies angrily with great enemy without putting haircut by three-step wave attack. Tenshi runs through the sky and becomes a comet and any enemies rush with god speed, that power to praise is exactly like a buddhist used from heaven to destroy demons."

neither does normal X5

"Finalist form" where five Digimon brought together with heart together. "Victory form", which is mainly at battle on the ground, is the figure which ultimately powered up with the flying ability acquired. "Meteobaster attack" which runs to the stratosphere by itself and becomes a meteorite and hits the enemy, not only the enemy, but also a large crater of hundreds of meters around the earth are carved into the ground. In addition, "Meteor Impact" which accumulates all energy in arms and is launched while knocking down enemies from near distance is a special technique to securely detain the opponent."

Neither of these states which specific Digimon are used to create it, just that five came to together for X5 and then that a Beelzemon is thrown in for X5B. So I think Shoutmon+X4+Beelzemon works fine. There's plenty of times where say, an Omnimon is made from something other than WarGreymon and MetalGarururmon and Omnimon's profile specifically states its from those two. For X5B, Impmons states his two friends are in there (Shoutmon. X5B) and then that his data was thrown in (Beelzemon).

Our X5 and X5B pages are stating each form shown in the anime in their page... but the DRB doesn't use those names at all in their profiles, so it's just saying "any five digimon can cause this guy".
