It is possible, but I would HIGHLY recommend that you do NOT do it.
You will have to dig deep down into the Mule Java APIs and couple yourself to them and also add a lot of your own error handling etc. and be wary of platform updates and the if the Java API changes.
Personally I would restructure you app to only have 'business logic' in scripts and let Mule do the flow lookups elsewhere.
You can even lookup flows in dataweave.
But here is a rough working example(Note you will have to harden this code yourself):
<flow name="test-flow">
<scheduler>
<scheduling-strategy>
<fixed-frequency frequency="100000"></fixed-frequency>
</scheduling-strategy>
</scheduler>
<set-payload value="bla bla" />
<scripting:execute engine="groovy" doc:name="Toggle flow" doc:id="2eb6f071-bdef-4d3d-926d-2565fcd62d33">
<scripting:code>
import org.mule.runtime.api.message.Message;
import org.mule.runtime.core.api.event.CoreEvent;
import org.mule.runtime.core.api.event.EventContextFactory;
flow=registry.lookupByName("another-flow").get();
thisflow=registry.lookupByName("test-flow").get();
msg = Message.builder().value(payload).build();
event =CoreEvent.builder(EventContextFactory.create(thisflow,
org.mule.runtime.dsl.api.component.config.DefaultComponentLocation.fromSingleComponent("add-location"))).message(msg).build();
result =flow.process(event);
</scripting:code>
</scripting:execute>
</flow>
<flow name="another-flow">
<logger level="ERROR" message="Another Flow #[payload]" />
</flow>
You need to fetch the current flow and the flow you want to call.
Using the Mule APIs - construct a Mule Event, Messgae, payload etc. You will also need to add any attributes you need etc.

Thanks Ryan for your response. I was able to achieve the functionality by using Java class instead of groovy.
