You are complicating the matter and weaken your design by replacing the square pipe with a flat bent plate.

I don't get the reason you can't get the weld done if the weld angles conforming to the limits set in the figure below:

Note there are other ways to built-up the weld around this joint. Also, an angle smaller than $$60^o$$ is permitted; however, in such a case, the weld is considered to be a partial joint penetration groove weld.

AWS D1.1 Specification Section 2.11 Skewed T-Joints indicates:

"2.11.3.1 Z Loss Reduction. The acute side of prequalified skewed T-joints with dihedral angles less than 60° and greater than 30° may be used as shown in Figure 3.11, Detail D. The method of sizing the weld, effective throat “E” or leg “W” shall be specified on the drawing or specification. The “Z” loss dimension specified in Table 2.2 shall apply."
