Chunky Ficus - Future Banyan?

[Muddy]

Good Morning All,
Thought I'd post some pics of a Ficus I'm hoping to develop into a banyan. Very new to bonsai, so I've decided to focus on some Ficus and try out a bunch of techniques. This victim was purchased as 2 plants in 8" pots a month ago.
Any consensus on the correct naming? Nursery said White Tigerbark Retusa. I'm calling it Ficus Microcarpa "Retusa". Can't find any references about the "white" naming?
I constructed a grow box for the little fellas while they develop.
There was a large knob on one plant where a heap of branches had sprouted & been left to grow. This was sawed off & turned to the inside. An area of bark on the opposing side was roughed up & the 2 tied with raffia.

The roots of both plants were sawed off to 1/3 & arranged to fit together. Left over roots were attached to the trunks to fill in empty spaces. Seeing how readily Ficus fuse & grow from root cuttings, I've simply pinned 2 roots to the trunks after slicing off a layer of bark & sealed with PVA. I like experiments! The root that mattered most was attached with the more accepted method of T-Cutting the bark & inserting the grafted root underneath. No cut paste on hand, so I soaked a strip of paper towel in PVA & wrapped the wound.

Trimmed off what was growing in the wrong places, wired the branches out & It's been growing great ever since. Still pushing out new growth, but I guess they don't slow down much in Brisbane.

Thanks for looking!

Should turn out fine, keep up the photos

I decided that I wasn't happy with the direction I was taking these two ficus. Trying to cover up the flaws of one tree by combining it with another just seems to multiply my problems
Time for a repot, prune & change of direction.
Plenty of good root growth filled out the whole grow box:

Top growth had been left to grow:

Roots washed to see what we're working with:

The two trunks pushed apart after the raffia loosened over time:

New root growth has been crazy. Better sort these out before it's too late to uncross them:

Failed root graft where I cut through the bark & secured the cut end against the trunk with a small nail:

The root graft where I cut a flap in the bark & inserted the cut end underneath the bark. Paper towel soaked in PVA used to seal the graft:

Here's the same graft with the blackened paper towel/glue mess removed. Completely fused. There is a gap where the bark hasn't joined, but I'm hoping this closes over time:

Same graft, different angle:

After separating the two trees, it was clear that having them together has hindered root development on one side of both trees:

Trunk #1 root pruned & cleaned up, ready for it's own home. No more sharing a room with your brother

That's better! Free to do it's own thing again:

Trunk #2 cleaned up & showing it's good side:

Trunk #2 has a bad side. No root growth at all on the side that was against the other trunk:

Trunk #2 root pruned & chopped:

Repotted & surrounded by some cuttings from it's top half. Hopefully I can graft one of these to fix the lack of roots on the back:

It's been a fun project so far. Looking forward to getting some branches set in the next year.
Thanks for looking!
