I think that's the point for most UBI proposals. The most cash-like welfare programs are TANF and SNAP, they pay out on the order of $250 (depending on state), are temporary, hard to obtain, always under danger of being cut, etc.

UBI is an appealing replacement that's universal (more resistant to cuts because it's more popular), pays out more, has no discontinuities which result in welfare traps, etc.

The goal should not be to increase welfare recipients but to increase quality of life and social outcomes. For instance a jobs program like the Green New Deal would probably "eat into welfare checks" as people become ineligible through earnings.
