I did, years ago! I never properly wrote it down, but let's see what I remember. Allow me to introduce you to:

Sonic Sentai Orchestranger
So the main team of four are based around the four main parts in an orchestra, and they transform with the "Tuning Changer", a wrist mounted changer that they load the gimmick item into - a CD-like colourful disc - and spin it to change.

OrchestRed - Themed around the String Section, specifically a violin. Armed with the prsonal "Bow Blader", a sword themed after a violin bow. A virtuoso player with a passion for improvising, OrchestRed is squad leader because he possesses the "Violin Orchestrecord", slowly mellowing out from a spotlight happy egotist to a calm and collected leader.

OrchestBlue - Themed around the brass section, specificallya trumpet. Armed with the "Slider Shooter", a trumpet/trombone gun that I haven't just stolen from Ibuki. A mellow, laid back jazz enthusiast, OrchestBlue is the calm and mellow heart of the team.

OrchstGreen - Themed around the woodwinds sction, specifically the flute, and armed with the "Reed Rod", a staff based on a flute. OrchestGreen is a music teacher - a perfectionist, especially for herself, OrchestGreen pushes the team to new hights.

OrchestPink - Themed around the percussion section, specifically a drum. Wields the Snare Shield, a shield based on a snare drum. A blunt young woman, OrchestPink tends to act without thinking, although maybe someday she'll become a better team player.

Each member of the team also has a MetroSaber, a sword based on a Metronome, which you can make tick for a boosted attack. And of course, you can combine their unique weapons together into the Sonicannon.

A few episodes in, the team are met with a new member, one representing a far more modern brand of music - OrchestSilver, armed with his guitar-themed weapon and unique changer, he acts on his own, clashes with the red for a few episodes, before they learn to harmonize. OrchestSilver can switch between his main mode, and a Bass Mode, which gives him some funky black highlights in his suit.

Also also you could probably add in "OrchestIdol" as an Extra Hero but that's a new idea from just now, I don't have anything deeper behind it.
