I messed up planting my hedge – is it worth attempting to dig up and adjust?

So I planted my rosemary hedge today at the front of my house, they are small plants only 30cm high (the biggest I could get). I somehow got tunnel vision while planting and didn’t realise my straight line was becoming more of a slight diagonal :/ There’s a drift of probably about 20cm over 6 plants.

Firstly is it even worth worrying about or over time will it just become negligible as they grow larger? Or if it is worth correcting does anyone have any tips on how to adjust the positioning slightly without damaging the roots accidentally 😬
