[Marvel] Did anything meaningful other than Deadpool and Wolverine ever come about due to the Weapon X project?
gpt
that depends. 

Are you talking about the American/NATO Supersoldier program, of which, Weapon X was the tenth successful product? If so, Captain America, some of the research into replicating Doctor Banner's hulk condition, Fantomex, "The World", and a number of other successful "weapons" have been developed as part of "Weapon Plus". 

Are you talking about Weapon X (weapon 10)  - the particular research project into regeneration and cybernetic implants that produced Wolverine? IF so, yes - Sabretooth (his healing factor may have been enhanced, but he was working with the program and was next to receive the adamantium if Logan hadn't made that impossible) Cyber, and a number of other enhanciles (NOT including deadpool) were modified by the program, whose data and samples went on to be used in creating X-23, deadpool, Lady Deathstrike, the many X-23 clones, as well as giving Dakken his adamantium-coated claws.
