[Feature Request]Can I use BedrockChat's Bot API as a multi-agent?

## Describe the solution you'd like

Can I use BedrockChat's Bot API as a multi-agent?

## Why the solution needed

We are increasing the number of Agent tools in BedrockChat, such as for DB access, but we are concerned that the accuracy of complex processing will decrease due to the increased number of tokens. This may require modification, but is it possible to use the Bot API as a sub-Agent?
We are currently working on implementing sub-agents at strandsagents, but it is taking time to improve the accuracy of the AI ​​agent development.

## Additional context

Add any other context or screenshots about the feature request here.

## Implementation feasibility

Are you willing to collaborate with us to discuss the solution, decide on the approach, and assist with the implementation?

- [ ] Yes, I am able to implement the feature and create a pull request.
- [ ] No, I am unable to implement the feature, but I am open to discussing the solution.

The request names BedrockChat's Bot API and ongoing sub-agent work at strandsagents, but no files, tests, or entry points. Start by tracing the Bot API and reviewing how agent tools are handled; the work is complete only after a multi-agent approach, scope, and acceptance criteria are agreed.
