I thought long and hard about having my Hohner Club II de-clubbed. You can learn fairly easily to avoid the gleichton and take the missing note from the other row. I had no problem provided I only played tunes on it which I didn't play on other boxes, and the gleichton does have some advantages especially when holding right hand chords to accompany songs. Nevertheless this did involve making a conscious effort to deviate from long-engrained playing habits and I eventually took the plunge to convert it.
As a beginner you have probably made the right decision, as it would be confusing for a learner to have two boxes with different layouts. For a more experienced player who acquires a club I would suggest you don't rush to convert it but see if you can get used to the difference, and whether that brings you any benefits. I'm still not entirely sure I made the right choice.
