Gravel bed / splash guard around the facade subsequently

Hello everyone, I probably posted this topic in the wrong forum, so here is the question again:

We moved into our new house in the first week of October last year and immediately completed the exterior paving ourselves. In doing so, we paved the area including the transition up to the house facade. Now, after a few months, it seems somewhat sterile and monotonous to us. For example, I am missing a gravel bed around the house to loosen up the appearance. So we are considering adding this afterwards.

This approach is purely for aesthetic purposes. We have a roof overhang of 1.00m so that even during heavy rain the area directly next to the facade hardly gets wet, so I think we don’t have to worry about rainwater infiltration? You can also see a dry strip in this area even during heavy rain...

Back then, we laid dimpled membranes immediately next to the facade, had to fill in with sand, then laid 10cm of gravel underneath, and 8cm thick paving stones lie on top. (20x30 paving stones)

We are now considering removing 2 rows of stones. This would create a 40cm wide strip along the facade. To accentuate the whole thing, we now want to set 10x10 granite pavers as an edge and fill the remaining 30cm to the facade with gravel. Since the paving stones to be removed are only 8cm thick, the gravel layer would also be 8cm thick, with gravel directly underneath.

Do you see any problems with this? What should one pay attention to?

Thanks and regards

I am just an amateur, but I can't imagine that there should be any problems there. Currently, you have the plates on it, and they would also let water through.. -> just like gravel.
