How to lay stepping pavers and pebbles over concrete?

[Ros2]

Hi, I’m wanting to lay rectangular limestone pavers on top of existing concrete down the side of my house, with pebble stones in between and down the sides.   
firstly, can I do rhiis?  Are there any issues, I’m thinking of drainage?   Any advice is appreciated.

I hope this does'nt come too late but I'm concerned you will block your weepholes if you do anything above the current level of the path. The weepholes already look like they have been slightly encroached on by the concrete path being too high. The last thing you want to ddo is prevent water exiting weepholes. You can imagine the consequences if water can directly enter the weepholes due to the new heights of pebbles and pavers. I would actually first ensure there is clear space and drainage away from the weepholes. This may involve removing sections of the concrete path especially towards the front sunny part of the building in the photo where the weephole appears to be partially below the concrete path. Tree roots from the established trees alongside will cause further lifting and shifting so you should factor that in should you decide on paving in future.

Thanks Apple Blaq.  
I appreciate all the advice I can get.  I haven’t started this project yet as I’m waiting on a small Reno job first.  
I’ll have a good look at the weep holes and may need to dig up a bit of concrete as you suggest.   Thanks again. Ros
