Technique for connecting a tile vertically next to a brick

Question

I'm trying to create this effect, where a 1x1 half-circle tile seems to 'stick out of' a 2x2 brick at 90 degrees:

This is easily achieved with a 1x1 tile with light attachment, as seen here from the back:

However, that particular piece is quite expensive in my chosen color (either orange or dark orange).

I've tried using a technic axle-and-pin connector, but it looks very bulky and the pin itself is also not available in (dark) orange:

I've also tried various brackets in different configurations, but since they're all square, the edges stick out from under the half-circle tile.

Are there other ways to achieve the same, or a similar looking effect?

Answer 1

Some ideas given the color constraints (all used parts are available in Orange, except those not visible). Perhaps none are very compelling, but they might point you in a different direction.

If you're not afraid of stressing bricks a bit (only during (dis)assembly - when assembled, there's no stress), using Hinge Plate 1 x 2 Locking with 2 Fingers on Side and 7 Teeth (50340) :

This next one doesn't actually work as pointed out in comments - the rod attached to the hand is too thin to stay put. Leaving it here in case someone knows of a trick to make it work anyway. When it's acceptable that the tile is slightly off angle, using Hand (983) and Technic, Brick 1 x 1 with Axle Hole (73230) :

Using Slope, Curved 1 x 1 x 2/3 Double (49307) instead of the tile :

And finally, a very rough approximation of the shape using Hinge Plate 1 x 2 Locking with 1 Finger on Side (44567) (assuming your requirements are quite flexible) :

Answer 2

Perhaps too straightforward: placing tiles between studs is a legal technique (so are plates by the way if the studs where you insert the plate between are hollow):

Answer 3

I'll suggest using a 1x1 plate with clip, recessed half a stud by means of a jumper plate:

I haven't tested this physically, but I assume that the clip will be under stress since (in this assembly) the round tile won't fit through the entire clip.

If you're OK with using dark orange, then you can use 1x2 plate round with some SNOT to achieve the effect:
