There is absolutely no reason to do this.
Any reasonable micro-controller can build merkle tree roots
significantly faster than is necessary.
1 Th/s walks the nonce range once every 4.3ms.
The largest valid merkle trees are 14 nodes high.
That translates to 28 SHA256 ops per 4.3ms or 6511 SHA25
The goal is to have an opportunity cost to breaking the rules.
Proof of Burn is a real cost for following the rules.

The alert system filters based on the clients version number.
The ubuntu bitcoin ppa is dynamically linked to openssl unlike the
binaries available from bitcoin.org
There is no way currently to notify users of 0.9.0 w/ static linking
without also notify 0.9.0 w/ dynamic linking.

The ratio of honest miners that mine the first block they see is > 0.5
Your proposed solution would reduce that ratio to 0.5
In other words your proposed change would make the attack you describe
easier not harder.

If you're only interested in storing the best chain then a fairly simple
schema is possible.
CREATE TABLE blocks (
hash bytea NOT NULL PRIMARY KEY,
index integer NOT NULL UNIQUE,
CONSTRAINT block_hash_size_check CHECK ((octet_length(hash) = (256 /
8)))
);
CREATE TABLE transaction_inpu
