Say someone sent some BTC to an output with a script of math operations that are equivalent to a complex equation. The input script, or what the redeemer of these BTC needs to supply, is the solution to this equation. The BTC are thus a "bounty" to solving this equation. With a limit of 10kb and 201 instructions, one could come up with some fairly complex equations. By including the text "bounty" in the script, others could be made aware of it.
Has anyone else thought about this? Do you think we will ever see this become a feasible idea?

Example 1: find the square root of 9
ScriptPubKey: BOUNTY OP_DROP OP_DUP OP_MUL 9 OP_EQUAL
ScriptSig: 3
Explanation: squares the input and checks if it is equal to 9

Note: OP_MUL is currently disabled...

Example 2: find a SHA256 hash collision
ScriptPubKey: BOUNTY OP_DROP OP_2DUP OP_EQUAL OP_IF OP_RETURN OP_ELSE OP_SHA256 OP_SWAP OP_SHA256 OP_EQUAL OP_ENDIF
ScriptSig:
Explanation: Check that string1 and string2 are not equal, then SHA256 each one and check that they are equal
