Grand Kids Riding up front?

[Offroad]

I've always enjoyed riding around the neighborhood (5-10mph) with grand kids in front of me.
I've always felt that was the safest place (I'm sure they won't fall off) and most enjoyable for them (hard to see around a big fat man and gives them a more realistic view of what it's like to ride a motorcycle).
I have 3 problems I want to fix:
1. I want a small set of extended handle bars for them to hang on to
2. I a set of foot pegs for them, extended out (away from engine) and up (for shorter legs)
3. I want a way for them NOT to get burned by the engine (some type of shield or maybe something they wear on their legs)
Does any one have the same idea? Have you solved problems 1,2 or 3? How?
If they are small enough their legs can't reach the engine, but as they get bigger it becomes a problem.
Thoughts?
