Two needle sewing a seam like that using a standard home machine would not be the best approach. If you have a two spool/two bobbin threading system you would be alright. But TMK those are found only on specialized industrial machines. Home machines using a single bobbin zig zag the bobbin thread between the two needles resulting in a weak seam effective only for decoration and not for structural integrity. IMO a flat felled/modified french seam is a better choice for home use.
