Will I get rose replant disease if I replace rose after only 6 weeks?

I bought 2 roses for an arch, but now they’ve just started blooming, I dislike the colour and want to replace ( knew I should have gone to DA).  Question is, they’ve been in for circa 6 weeks, so do you think I’ll get away with replacing in same spot or do you think I could encounter rose replant disease?  Thanks.
