Turning standard guitar into a baritone?!? daddario extra lights ej15 to daddario heavy ej18

Can&afford a baritone guitar so I am putting the heaviest strings I can find on my dreadnaught they happen to be daddario phosphor bronze ej18 .014-.059 I used to have daddario extra lights ej15s on so you can get a sound comparison of them. I managed to get the guitar into &tuning&(BEADFwith the heavy strings on without really any complications. I think it sounds ok but I will leave up to you. I&pretty sure it&at least a cheap way to get that baritone sound quick and easy. I wouldn&recommend you did this on an expensive guitar as the extra tension of the thicker strings (albeit tuned with much less tension) could potentially do damage to your guitar. This cheap thing is built like a tank however and I haven&even needed to adjust the truss rod
